• Dual Input Channels Synchronism 0.5 seconds
• Test Input
• LED Indications for Power on, Inputs and Outputs
• 3 NO/1 NC Relay Outputs
• Quick Release Connector Blocks

The JSBT4 has two inputs, both of which have to be closed in order to keep the safety output contacts closed. A short circuit between inputs A and B will cause the output contacts to open. The inputs can be continuously short circuited without damaging the safety relay. For the outputs to close, the test input must be closed. The test input is intended to monitor if contactors or valves have dropped/returned before a new start is permitted.
