100% Original and Brand New MTL2000 range MTL2215 Switch operated relay ~ IS output product has been discontinued.

The MTL2215 enables either one or two separate IS circuits in a hazardous area to be relay-contact controlled by a single on/off switch or logic signal in a safe area. Applications include the calibration of strain-gauge bridges, changing the tone of an IS sounder, the testing of IS fire alarms, and the transfer of safe-area signals into an annunciator with IS input terminals not segregated from each other. The output-relay contacts are certified as ‘non-energystoring’ apparatus, and can be connected to any IS circuit without further certification, provided that separate IS circuits are such that they would still remain safe if connected together.

Safety description (each channel)

Non-energy-storing apparatus: relay contacts may be

connected to any certified IS circuit in Zone 0 without further

certification

Note: The 2-pole changeover contacts may be used to switch separate IS

circuits only if these remain intrinsically safe when interconnected, since the

two sets of relay contacts are not segregated from each other
