How do I configure and install the Siemens MOD-16 Output Driver for my annunciator system?

[DiCassidy]

Setting up your Siemens MOD-16 Output Driver for your annunciator system requires careful attention to detail. Here's a breakdown of the configuration, installation, and electrical considerations:

1. Dipswitch Settings: Determine your output type to set the dipswitches correctly.

   • For LED outputs: Open all dipswitches on S1 and S2. This configuration activates the internal 2.7K ohm current-limiting resistors, protecting your LEDs.
   • For 24V lamp outputs: Close all dipswitches on S1 and S2. This bypasses the current-limiting resistors.

2. Installation Procedure:

   • Safety First: Always disconnect power to the entire system before any installation or wiring work.
   • Mounting: Securely mount the MOD-16 in a module space on a System 3 type rail using the provided screws.
   • Connections: Connect the MOD-16 to the MOI-7 module using the 10-position ribbon cable (Part Number 555-190940). If connecting to another MOD-16 module on a different rail, use the optional cable (Part Number 555-190941).

3. Electrical Ratings: Understanding these ratings is vital for safe and reliable operation.

   • Active Module Current (5VDC): 2mA
   • Active Module Current (24VDC): 0mA + 50mA per active output
   • Standby Module Current (24VDC): 2mA
   • Maximum Output Current: Each output can handle up to 50mA.
   • Wiring: Use the appropriate wire gauge for your connections. Always adhere to the National Electrical Code (NEC) 760 and all local electrical codes.

4. Connection to SR-35 Module: If you're using an SR-35 module with your MOD-16, a specific jumper setting is required.

   • Jumper Configuration: Ensure jumpers P1-P8 on the SR-35 are set to position B.
   • Terminal Connections: Follow the wiring diagrams in the manual for precise connections between the MOD-16 and the SR-35.

5. Additional Resources: Always consult the following manuals for comprehensive details:

   • SR-35 manual
   • PS-35 manual
   • PSR-1 manual
   • Power Supply Connections: Carefully connect the power supply terminals as specified in the manuals. Always comply with all wiring regulations.

By following these steps and referring to the documentation, you can effectively integrate and operate the Siemens MOD-16 Output Driver within your annunciator system.
