GE IC694MDL916 Output Module, Isolated Relay
The 4 Amp 16 Point Relay Output module provides 16 Form A relays for controlling
output loads. The maximum output switching capacity of each circuit is 4 Amps. Each
output point is isolated from the other points, and each point has a separate common
power output terminal. Outputs provide a high degree of noise immunity, minimizing
the need to add external snubbers. The relay outputs can control a wide range of
output devices, such as: motor starters, solenoids, and indicators. The user must
supply the AC or DC power to operate the field devices.
This module is available as a PACSystems RX3i module (catalog number
IC694MDL916), illustrated at left, or as a Series 90-30 PLC module (catalog number
IC693MDL916). The RX3i version is only compatible with a PACSystems RX3i CPU.
The Series 90-30 version can be installed in any I/O slot in a PACSystems RX3i or
Series 90-30 PLC. See the next page for details of specific CPU version requirements.
Module MDL916 can be used with a Box-style (IC694TBB032), Extended Box-style
(IC694TBB132), Spring-style (IC694TBS032), or Extended Spring-style
(IC694TBS132) Terminal Block. Extended terminal blocks provide the extra shroud
depth typically needed for shielded wires. See the PACSystems RX3i System Manual,
GFK-2314 revision B or later for more information about terminal blocks. Terminal
Blocks are ordered separately.
A DIP switch on back of the module is used to select the outputs’ default mode: Force
Off or Hold Last State. The module must be removed from the backplane to set this
switch.
Individually-numbered LEDs indicate the ON/OFF state of each output. The red/green
TB LED is green when the module’s removable terminal block is locked in place. It is
red when the terminal block is not locked.
Module IC694MDL916 reports Addition of Terminal Block, Loss of Terminal Block,
Hold Last State Configuration Mismatch, and Module Over Temp messages to the
RX3i CPU. Module IC693MDL916 does not report diagnostic status to the CPU.
The red bands on the door card show that MDL916 is a high-voltage module.

Diagnostic Information Field side terminal block presence detection reported to CPU (for RX3i
only)
* When this module is used with DC power supply IC695PSD040 or PSD140, special precautions should be taken
because dropouts in the source voltage will be seen by this module and may cause relay dropouts.

Setting the Output Defaults
The DIP switch on back of the module determines how the outputs will operate if the CPU is set to Stop Mode or
loses communications with the module. The Outputs Default Mode selection made with the DIP switch must
match the selection made for this feature in the module’s software configuration. If the two do not match, a
warning message is displayed in the fault table.
The module must be removed from the backplane to set this switch. Note that there are two DIP switches on the
module. Only the upper switch is used.
Outputs Default mode DIP Switch
Closed (left) = Hold Last State
Open (right) = Force Off
Not Used
With the Outputs Default Mode switch in the right
(open) position, the outputs will turn off whenever
communication with the CPU is lost.
When the switch is in the left position, the outputs
will hold their last programmed value whenever
communication with the CPU is lost. Backplane
power must be present to Hold Last State.
Otherwise, the module will default outputs
regardless of the DIP switch setting.
