TM3DQ16R / TM3DQ16RG Wiring Diagram
These expansion modules have a built-in removable screw or spring terminal block for the connection of the outputs and power supply.
The following figure illustrates the connections between the outputs, the actuators, and their commons:
* Type T fuse
(1) The COM0 and COM1 terminals are not connected internally.
(2) To improve the life time of the contacts, and to protect from potential inductive load damage, connect a free wheeling diode in parallel to each inductive DC load or an RC snubber in parallel of each inductive AC load, or a varistor on either type of load.
A Source wiring (positive logic)
B Sink wiring (negative logic)
NOTE: When you use the TM3 expansion module with a TM3 Ethernet bus coupler, you must connect an RC snubber in parallel of each inductive AC load.
For information about 24 Vdc power supply, refer to DC Power Supply Characteristics.
