  • Operates on 12 or 24 VDC input power for flexible installation
  • RS-485 multidrop communication supports 2-wire or 4-wire wiring
  • Up to 16 modules per Intelligent System Controller via DIP switch addressing
  • Controls elevator systems with support for 128 floors

Access-control output module with 16 relays

The Astro Gaming LNL-1200-S3 Output Control Module provides 16 Form-C relay contacts rated at 5 A and 30 VDC for switching door locks, alarms or other access-control loads. It accepts 12 or 24 VDC input power and includes two dedicated digital inputs for tamper and power-failure monitoring. The board communicates over 2-wire or 4-wire RS-485 with on-board termination jumpers and DIP-switch addressing.

RS-485 multidrop limits and addressing

Up to 16 OCMs can share a single RS-485 bus connected to an Intelligent System Controller, each counting as one device on that controller. Communication uses standard RS-485 signalling at 485 kbaud; the installer must set a unique DIP-switch address on every module and fit termination jumpers only at the physical ends of the bus. The 2-wire or 4-wire choice applies to the whole multidrop segment.

Power supply and elevator capacity check

Verify that the site power supply delivers stable 12 or 24 VDC at sufficient current for all 16 relays plus the module electronics. Confirm the Intelligent System Controller firmware supports Series 3 OCMs and that the elevator application does not exceed 128 floors. Ensure cabinet space allows wiring access to the relay terminal blocks and status LEDs.

Questions about this item

How many relays does the LNL-1200-S3 provide and what contact rating do they have?

The module supplies 16 Form-C relays, each rated at 5 A and 30 VDC for load switching.

What happens when I connect the module to 12 VDC versus 24 VDC input power?

The unit operates on either 12 or 24 VDC; both voltages power the same 16 relays and two dedicated digital inputs for tamper and power-failure monitoring.

What does the RS-485 multidrop limit of 16 modules per controller mean for my installation?

You can connect up to 16 OCMs on a single RS-485 bus to one Intelligent System Controller, using 2-wire or 4-wire wiring with on-board termination jumpers.
