Installing Output Modules
To install an output module into the controller, remove the bezel assembly
from the case (See Removing Bezel Assembly, page 5). Locate the correct
output module socket (OP1, AL1, or AL2/OP2, see Figure 6, Hardware, 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.
Note: For Valve Positioner models, the circuit board markings have the
following meaning:
AL1 - Open Output
AL2/OP2 - Close Output
OP1 - Alarm #1 Output
OUTPUT MODULE “OUTPUT ON” STATE
Relay Normally open contact is closed
Logic/SSR Drive Source is active.
Triac Solid state switch is closed.
Typical Connections
Relay:
Type: Form-C (Form A with some models. See Ordering Information.)
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).
Logic/SSR Drive:
Type: Non-isolated switched DC, 12 VDC typical
Drive: 45 mA Max. Can drive multiple SSR Power Units.
Triac:
Type: Isolated, Zero Crossing Detection.
Rating:
Voltage: 120/240 VAC.
Max. Load Current: 1 amp @ 35°C
0.75 amp @ 50°C
Min. Load Current: 10 mA
Off State Leakage Current: 7 mA maximum @ 60 Hz
Operating Frequency: 20 to 400 Hz
Protection: Internal Transient Snubber, Fused.
SELECT AC POWER (115/230 VAC)
The AC power to the unit must be selected for either 115 VAC or 230 VAC.
The selector switch is located inside the case near the rear of the unit on the
main circuit board (see Figure 6, Hardware, or label on outside of case). The
unit is shipped from the factory with the switch in the 230 VAC position.
Caution: Damage to the controller may occur if the AC selector switch is set
incorrectly.
