Ultra Electronics, NSPI now offers a new fiber optic transceiver for Safety Shut-Down applications used to convert up to ten contact closure inputs into fiber optic signals for transmission over a single fiber optic link. Upon activation of the inputs, the receiver module receives the transmitted signals and de-energizes the corresponding, on-board relay operating in a fail-safe mode for switching critical systems.

Each transceiver module includes two contact closure inputs and is capable of driving up to ten inputs by cascading additional dual channel input modules. A de-pluggable screw terminal on the bottom of the module is provided for connection to the input signal. An integrated backplane allows for communications between modules with no external inter-modular connection. Each transceiver has a single optical port for use with multi-mode or single mode optical fiber with transmissions at 850 nm or 1300 nm using industrialized ST/SMA connectors.

SPDT Form C relay outputs are provided for each channel capable of driving resistive loads with a maximum switching power of 120W, 250VA, and maximum switching current of 4A DC, AC.
