APPENDIX B. ELECTRICAL AND DATA CONNECTIONS
IS-2200CA/4500CA INVERTER POWER SUPPLY
B-12 990-412
PIN NAME DESCRIPTION
TB4-13
INT +24VDC GND I/O COM pin. This pin is internally connected to the +24VDC GND
TB5-1
TB5-2
EXTERNAL
VOLTAGE
Secondary voltage input pins. Internally connected to the IT XFMR sense connector.
If IT XFMR sense cable not used may be connected directly to electrodes.
TB5-3 EXT. COM
For internal Sink (pull down) Connect to pin 1. For Internal Source (push up)
Connect to pin 4.
To activate input in Sink Mode, connect inputs to INT +24VDC GND (I/O COM)
To activate input in Source Mode, connect inputs to INT +24VDC
For External Sink attach PLC +24V. For External Source, attach PLC COM
TB5-4
THERMOSTAT
COM
Common input for Transformer Thermostat through the XFMR Sense connector
For Internal Sink operation, connect to INT +24VDC GND (I/O Com)
For internal Source operation, connect to INT+24VDC
For External Sink, connect to PLC COM For External source, connect to PLC +24V
TB5-5 THERMOSTAT
If the XFMR Sense connector is not used, this pin should be connected to the
appropriate voltage (Sink or Source) If the XFMR Sense connector is used this pin
should be left open.
TB5-6
TB5-7
EXTERNAL
CURRENT COIL
Current coil input, used for secondary current feedback. Internally connected to the
IT XFMR sense connector. If ITXFMR sense cable is not used, may be connected to
external current coil.
TB5-8
INT +24VDC GND
(I/O COM)
COM pin. This pin is internally connected to the +24VDC GND
TB5-9
to
TB5-12
NO CONNECTION
TB6-1
VALVE POWER
(SOL)
Power input pins to drive the solenoid valve.
Input 120VAC or 24VDC power.
TB6-2
VALVE COM
(SOL)
COM pin for the solenoid valve.
TB6-3
TB6-4
VALVE1 (SOL1)
VALVE2 (SOL2)
Solenoid valve output pins. 36: VALVE1 (SOL1); 37: VALVE2 (SOL2)
These pins are closed for the duration of the STAGE 2 input.
Output between SQD and HOLD.
When the off time (OFF) is set, this pin is output between SQZ and HOLD after the
second sequence.
The contacts are rated at 120V AC or 24V AC/DC at 0.5A (semiconductor
switches).
Use a solenoid valve with a current capacity of 0.5A or less.
NOTE: when using DC solenoid see note *3
