They have universal inputs (10 thermocouple and 4 RTD types, voltage, and current). Standard features include remote reset capability. Outputs include normally open (form “A”) and normally closed (form “B”) relays. Form “A” and form “B” relays can be set up for each setpoint output and logically linked to emulate a form “C” output. **==> picture [58 x 15] intentionally omitted <==** **----- Start of picture text -----**
