Watlow 981 series temperature controllers.

These have been removed from recent equipment, manufactured around 2001.  Condition varies between brand new and some with slightly tatty front panels  Supplied with mounting hardware intact.  I may also be able to supply other parts associated with these, including type K thermocouples (in "bullet" tube), thermocouple sockets, mains heater elements, mechanical or solid state relays etc.  Also available, nice metal cases with mounting holes precut for these Watlow controllers, including mains wiring etc.

Model number 981C-15CE-JSGG.  Specifications:

• 100 to 240V ac/dc nominal, horizontal mounting
• Standard software, (4-file, 6 step per file, program capability)
• Basic thermocouple signal conditioner (excluding types B,R and S)
• Second Digital Event option (one event digital is standard on all units)
• Output 1: Switched DC or open collector, isolated output
• Output 2: Electromechanical relay, From C, 5A with RC suppression
• Output 3: Electromechanical relay, From C, 5A without RC suppression
• EIA/TIA-232.EIA/TIA-485 communications, opto-isolated
