OUTPUT MODULES

The main control, optional alarm, and optional cooling output sockets must

be fitted with the appropriate output module. Output modules are shipped

separately and must be installed by the user.

Output Variations Without RS-485 Option

The Dual Alarm or the Cooling with Alarm output, without the RS-485

option, has independent outputs. Therefore, the cooling output and/or alarm

output(s) can be installed with any combination of output modules.

Output Variations With RS-485 Option

The Dual Alarm or the Cooling with Alarm output, with RS-485 option,

does not have independent outputs. In this case, the cooling output and/or

alarm output(s) must have the same type of output modules installed since

they share the common terminal.

Installing Output Modules

To install an output module into the controller, remove the bezel

assembly from the case (see Removing Bezel Assembly). Locate the

correct output module socket (OP1, AL1, or AL2/OP2, see hardware figure

or label outside of case) and plug the output module into the socket. No

re-programming is required. If changing an output module type, be sure the

appropriate output interface wiring changes are made. Re-install the bezel

assembly when complete.

Relay

Normally open contact is closed.

Logic/SSR Drive

Source is active.

Triac

Solid state switch is closed.

Relay:

Type: Form-C

Rating: 5 Amps @ 120/240 VAC or 28 VDC (resistive load), 1/8 HP @ 120

VAC (inductive load).

Life Expectancy: 100,000 cycles at maximum load rating. (Decreasing

load and/or increasing cycle time, increases life expectancy.)
