Home / Relay Terminal Module Selector Guide

Most BASE Modules are supplied with 1/4" nylon mounting standoffs. This hardware is economical, installs fast in the field, and allows a pc board to be easily removed with no messy residues.
Most Prewired Cabinets that we've built for Elevator Interface use the RTM-8P relay modules. Search our Prewire Database for Elevator Interface Cabinets here.
Model
Description
The RTM-8 Relay Terminal Module provides 8 individual SPDT relay sockets together on one printed circuit board. Outputs terminals are provided for dry form-C relay contacts. Heavy duty 10A Idec RH Series Relays are ordered separately depending on desired voltage (12 or 24vdc).

The RTM-8 has input terminals for controling the positive or negative side of each relay coil for use with dry contact, +voltage, open colector or sink-type switching.

Each module has red LED status indicators and isolation diodes at each relay position.

Module size is 3.00w x 6.50h and includes manual and mounting standoffs.

The RTM-8 supercedes the RTM-8P and RTM-8N as of 10/1/05.

The RTM-8P/8N Relay Terminal Modules provides 8 individual SPDT relay sockets together on one printed circuit board. Outputs terminals are provided for dry form-C relay contacts. Heavy duty 10A Idec RH Series Relays are ordered separately depending on desired voltage (12 or 24vdc).

The -8P version has input terminals for controling the positive side of each relay coil. The -8N version controls the negative side of each relay coil for use with open colector or sink-type switching.

Each module has red LED status indicators and isolation diodes at each relay position.

Module size is 3.25w x 7.00h and includes manual and mounting standoffs.

Availability limited after 10/1/05 - superceded by the RTM-8 (see above)
