This optional hardware module provides two alarm drive outputs. LED indicators A1 and A2
are used to indicate alarm conditions as configured in the Alarm Menu.
OptionDescription:
Option 10: Dual alarm, N.O.
Option 22: Dual alarm, N.C. (Note: NC only when power
is applied to unit; otherwise NO)
Load Limits: Max. Load Current 1 A rms
Min. Load Current 0.5 mA rms
Power Factor Range 0.2 to 1.0 (can drive small
motors, solenoids, valves, and
contactors)
Max. Surge Current
Non-repeating for 1 second 7.5A
Max. I2T for fusing (0.01 sec) 4.5 amp-squared seconds (1 A -
ABC1 typical fuse)

RS-232
Communications
Option #30: RS-232 (one-to-one) Communications
Option Description: Provides a one-to-one connection between
the controller and an RS-232 port.
Computers, PLCs, or dumb terminals may
be used to set and access controller data.
6
RS-485
Communications
Option #31: RS-485 (one-to-many)
Communications
Option Description: Providesone-to-manycommunications.
If run exceeds 1000 ft., terminate the controller furthest from the computer by connect-
ing a 120-ohm, 1/4-watt resistor between terminals 13 and 14.
*Converter is supplied with a wallplug-mount power transformer.
7
Contact/Digital
Input with Alarm
Option Description: Dual function board (functions unrelated)
a. Output alarm is energized when either A1
orA2 isactive.
b. Digital input controls Remote Standby, Ramp-Soak
Run/Hold, OR Second Setpoint Select.
Option 40: Active when switch closed.
Option 41: Active when switch open.
Option 42: Active when 5 V input present
