At a glance
- Six Form C RelaysThe CR-6EA consists of six Form C relays in one six way changeover relay output module.
- Isolated Dry Contacts Per AddressA single isolated set of dry relay contacts, which can be wired as normally open or normally closed, is provided for each address.
- Built-In Loop IsolationThe module has built-in loop isolation.
- Contact RatingRelay contacts are rated 3A at 30VDC resistive load.
- Current DemandCurrent is 1.49mA with a blinking LED once every 5 seconds and 36mA at 32V assuming all six relays have switched once and all six LEDs solid on, with a relay pulse of 30mA per relay for 15.6ms under panel control.
- Rotary Address SettingThe first address is set from 01 to 94 on rotary address switches, the other modules are automatically assigned the next five addresses, and up to three unused addresses can be disabled.
- Unsupervised Controlled CircuitThe controlled circuit is not supervised.
- M200-SMB-MM Mounting RequiredThe module requires an M200-SMB-MM for mounting and uses removable plug-in terminal blocks with individual LED indicators.
Description
Six switched outputs sit in this changeover relay output module, which carries six Form C relays. Every address it occupies is served by one isolated set of dry relay contacts that can be wired normally open or normally closed, and switching is commanded by the control panel on demand. The circuit being controlled is not supervised.
Loop isolation is built in. Addressing runs from a first address set anywhere from 01 to 94, after which the next five addresses are automatically assigned to the remaining modules, and up to three unused addresses can be disabled. Mounting calls for an M200-SMB-MM.
The CR-6EA is a six way changeover relay output module for System Sensor Protocol systems, built around six Form C relays with built-in loop isolation. Each address is given a single isolated set of dry relay contacts, which can be wired as normally open or normally closed, so the control panel is able to switch the contacts on demand. The controlled circuit is not supervised.
Contact rating is 3A at 30VDC resistive load. Operating a relay draws 30mA per relay as a pulse of 15.6ms duration, with the pulse under panel control, while the module's maximum current is 1.49mA with a blinking LED once every 5 seconds, or 36mA at 32V assuming all six relays have switched once and all six LEDs solid on.

Electrically the contacts handle 3A at 30VDC resistive load. A relay pulse is 30mA per relay for 15.6ms under panel control, and demand peaks at 36mA at 32V once all six relays have switched once and all six LEDs are solid on, against 1.49mA where the LED blinks once every 5 seconds.

Addresses are set on rotary address switches: the first address is set from 01 to 94 and the other modules are automatically assigned the next five addresses, with up to three unused addresses able to be disabled. Individual LED indicators and removable plug-in terminal blocks are fitted, and the module mounts on an M200-SMB-MM, which is required. It falls under System Sensor Protocol Output Modules.
