ZL-RRL16-24 DC Powered Relay Module
Installation Instructions
Product Overview
The ZL-RRL16-24 is a 16-output DC powered relay module with LEDs, designed for 24 VDC coil operation. It is suitable for use with AutomationDirect's DirectLOGIC, CLICK, and Productivity 3000 I/O module series.
The module features 16 relays, each with a 1 Form C (SPDT) contact configuration. It is designed for mounting on a 35mm DIN rail.
Diagrams and Layout
The module features 16 relays (RL1 through RL16) arranged in a row. Each relay has three terminals labeled COM (Common), NO (Normally Open), and NC (Normally Closed). Terminal blocks (TB1 through TB16) are provided for connecting the relay contacts. Power input terminals are labeled GND and 24V.
Two jumpers, Jumper 1 and Jumper 2, are located at the top of the module for configuration.
Typical Internal Circuit: A single relay's internal circuit shows a coil connected to 24V and GND. The contacts consist of a common terminal (COM), a normally open terminal (NO), and a normally closed terminal (NC).
Cable Connector: A cable connector is present for input/output connections.
Jumper Settings: The module supports different I/O module series, including DirectLOGIC, CLICK, and Productivity 3000, configured via jumpers J1 and J2.

Installation Procedures
Remove or Install Relay
To remove a relay:
- Rotate the retaining clip away from the relay.
- Remove the relay from the module.
Reverse the procedure to replace a relay.
DIN Rail Installation and Removal
To install: Insert the upper tab of the ZIPLink module into the DIN rail. Rotate until firmly seated, then click to lock it onto the DIN rail. (Note: For clearance requirements, refer to the specifications section).
To remove: Insert a screwdriver between Tab 1 and the module. Pry up to release the clip from the DIN rail. Repeat for Tab 2.
ZIPLink Cable Removal
- Push the tab on the raised tip and hold.
- Pull the connector from the socket.
