To simplify mounting, the from -50 to +600˚F ( -45 to +315˚C). instrument design allows front-of-panel mounting. MODULAR CONSTRUCTION PROVIDES YOUR CHOICE OF CONTROL MODE AND VERSATILITY OUTPUT The Series 551 Controller features the latest advances Both on/off and time proportioning units are offered with in electronic temperature measurement and control SPDT relay, DPDT relay or output to drive a solid state including plug-in construction, providing ease of relay. replacement and interchangeability of modules. For versatility and convenience, even the relay is plug-in. PROTECTS AGAINST LEAD BREAK OR SHORTED PROBES The controller features lead break protection as well as built-in protection from a shorted thermistor probe. If such a problem arises, a high temperature situation is simulated, driving the meter upscale and the output will de-energize. 3.13.9 7/11/2000 6:28 AM Page 2 CP Scan#1:Desktop Folder:hold:950 Catalog:3.13.9.job: SPECIFICATIONS TEMPERATURE RANGES -50 to +600 ˚F (-45 to + READABILITY 315˚C) in five overlapping ranges.
