General Specifications

Controller Description
Control Functions: Dual PID+: two independent, event-selectable sets of control functions for each channel consisting of proportional, integral and derivative control plus reset windup inhibit and reset clipping. "Set 2" tuning is in effect when the enabling event is ON. Cycle time ranges from 2 to 15 seconds.
Time Proportioning: Two per channel (increase & decrease); clamp logic outputs for driving photo-isolated solid state relay.
Linear Outputs: Two outputs, each assignable to either channel as process variable or setpoint retransmit. 4-20mA or 0-16mA; maximum loop resistance, 600 Ohms.
Cold Junction Comp: ±0.01 degree/ degree over 15°C to 35°C ambient operating range.
Physical Characteristics Description
Overall Dimensions: 6" x 6" x 12 7/8" (w/o accessories); 10 lbs.
Mounting: 5 3/8" square cutout.
Power Requirements: 117VAC ±10%; 25W.
Operating Temperature: 0 to 40C; 85% max. RH, non-condensing.
Alphanumeric Displays: two 2-line, 20 character per line, Vacuum Fluorescent Display.
Setpoint Programmer Description
Setpoint Range: Full range of the controller.
Program Steps: 200 total steps; 99 programs, max.
Step Types: RAMP/SOAK (Standard), EOP (End of Program); LOOP; GOTO; GOTO_IF and PAUSE.
Step Time Duration: 0 to 99:59:59. (HH:MM:SS)
Delay Start: 0 to 99:59:59. (HH:MM:SS)
Guaranteed Soak: Program waits at the end of a ramp step until the process is within specified tolerance; programmable, per step, in 1 unit increments, per channel.
External Events: 16 programmable clamp logic outputs suitable for driving photo-isolated solid state relays.
Process Deviation Alarms: ±1 to 55 units, programmable per channel, per step.
Display Deviation Alarm Action: Flashing indication on front panel display plus clamp logic output; programmable to clear automatically or to require manual reset.
Deviation Alarm Action: Programmable to continue running; or pause until condition clears or until alarm is manually reset.
HI/LO Process Limits: Programmable per channel in 1 unit increments over full input range.
Limit Outputs: One each per channel, logic output suitable for driving photo-isolated solid state relay.
Control Inputs: External photo-isolated inputs provided for run, stop, reset and front panel lockout.
Recovery After Power Failure: Three power fail recovery modes: Normal (auto resumption of program); Hold (program and setpoint values at time of power fail); Run (selected program and step #).
