Please find below major data: SRB-C.44 (data sheet see page 8) – 3 safety enabling outputs, 1 monitoring contact – Dual-channel triggering for non-equivalent inputs – Suitable for reed switches due to current limitation and voltage limitation at input circuits – Selectable extras: Trailing edge function, Auto reset, cross-short recognition SRB-C.46 (data sheet see page 16) – 3 safety enabling outputs, 1 monitoring contact – Single- or dual-channel triggering – Suitable for signal processing of externally powered inputs SRB-C.47 (data sheet see page 20) – 2 enabling outputs, instantaneous,1 monitoring contact – 1 enabling output, drop-out-delayed 1 ... 30 sec. – Single- or dual-channel triggering – Suitable for signal processing of externally powered inputs – Selectable extras: Trailing edge function, Auto reset, cross-short recognition Safety relay modules SRB-C.46 and -C.47 with hybrid fuse As a further significant feature the modules SRB-C.46 and -C.47 are fitted with a so called hybrid fuse. In contrast to a fusible cut-out (glass tube type) the function will be restored automatically after a short circuit. As distinct from commercially standard electronic fuses, the hybrid fuse has a latch function and resets only after power down – power up. This kind of reset prevents the danger of an unintended restart in mode "Automatic start" after repairing a short circuit. 6 6 New products: New products: 1 1 Safety relay module Safety relay module SRB-C.45 (data sheet see page 12) SRB-C.45 With "long-life" feature provided by a complementary electronic circuit As the result of a complementary electronic circuit comprising photo MOS relays connected upstream of the safety releases, this new C.45 SRB component possesses the special feature that the mechanical and the electrical service life of the safety- orientated relay contacts have become approximately equal. With usual safety relay components, in contrast, a much shorter electrical service life compared to the mechanical service life arises from the switch load. This can be a particular technological disadvantage with applications with a large number of switching cycles, e.g. for the control of the working cycle of a machine. The complementary electronic circuit in the C.45 SRB component ensures that during the switching on or off of the safety releases, the electrical load is exclusively switched by the photos MOS relay, and that the relay contacts which switch at the same time remain free of the switch load, i.e. their electrical service life remains unaffected. The C.45 SRB component is suitable for 1 or 2 channel activation, either trailing edge, automatic start or cross fault monitoring, it has 2 safety queries available and one floating contact and one electronic feedback contact. The width of the component is 45 mm. Functional sequence Closing release: 1. Release is open 2. Relay contacts close 3.

Unlike to the above the circuit in 2-relay technique is not triggered by an own start relay. The initial start test and setting into operation is achieved by setting the channel relays into latch state in one step. Resulting from the different operations of relay modules in 2-relay or in 3-relay technique various functional possibilities are on disposition. Example circuit of a SRB module with three safety relays in power off state. The advantages of the 2-relay technique are quite obvious: • Primarily is the space saving in the control cabinet since the modules for 24 V generally are 22.5 mm wide only. • The second important advantage is the cost saving. From the safety point of view there is no difference between these two circuit techniques. But certain functional characteristics i.e. performing of initial start test as required in control categories 2 and 4 (see par. "Initial Start Test" on page 163) or start procedures in connection with feed-back signals are practically realized only with circuits using 3 (internal) safety relays. Example circuit of a SRB module with two safety relays in power off state. In all circuits only safety relays with positively guided contacts are applied. The majority of the circuits is equipped with pivoting armature relays, some others with cutout blade relays. 162 Input circuitry Input circuits as proposed below are sufficient in standard situations: Control category 1: single channel input without initial start test. Control category 2: Single channel input with initial start test. Control category 3: Dual channel input without initial start test. Control category 4: Dual channel input with initial start Examples of SRB modules with option "Initial start test" test. A dual channel safety circuit is not necessarily the answer to the Initial start test means the complete contact safety devices (i.e. light question if a moveable protective safety circuit needs to perform a test curtains) relay circuits may be gate needs to be monitored by one or run on power up prior to be set into needed to perform such a test by two Safety Limit Switches.

This is to be achieved either by using a separate multi-core cable ("shielded cable") for each channel or by fitting a Safety Relay with cross short recognition. Examples of SRB modules with cross-short recognition Relay circuits are generally designed SRB modules for inputs from safety devices fitted capable for with mechanical contacts. For safety external reasons the operating voltage for the powered inputs safety devices is sourced from the SRB modules. Connection of safety devices with non isolated contacts i.e. light barriers with semi-conductor outputs or from safety devices with outputs powered from own power supply needs suitable circuits (refer to appropriate data sheet). Connection of safety devices with isolated contacts is of course still practical. Examples of SRB modules for externally powered inputs from electronic devices.

A typical example are motors which can be slowed down to stand still by generatoric brake mode more rapidly rather than by immediate shut down of the energy. In this case drift to stand still will take more time and is therefore more dangerous. Time delayed enabling outputs are also taking care that fuses in intermediate circuits of closed loop drives and also the drives itself are not being destroyed. The delayed shut down of energy, adapted to the maximum breaking time of the drive serves as a protection in the case of failure and protects against unintended restart. Depending on the application SRBExamples of SRB modules with time delayed enabling outputs modules with time delayed enabling outputs – some up to 30 seconds – are available. 165 Scope of products (continued) Scheme of The delay function of drop out delayed enabling outputs in SRB time delayed modules is carried out by using enabling 2 independent time channels each outputs triggering 2 independent safety relays (does not apply for SRB type C.16).The circuit also corresponds to EN 60 204 : 1998-11 for E-stop signals.
