ABB JSR1T 0 expansion relay 6A 24 DC

Why Choose the ABB JSR1T 0 2TLA010015R0000 Safety Expansion Relay?

The ABB JSR1T 0 2TLA010015R0000 is a dependable safety expansion relay designed to increase the number of safety outputs available from a compatible safety relay. Part of the ABB Jokab Safety JSR1T range, this zero-delay version provides four normally open safety outputs and one normally closed information output for industrial machine safety applications.

The JSR1T is designed to operate together with a safety relay, which controls and monitors the expansion module. It can be connected for either single-channel or dual-channel operation. Internally, mechanically operated relays K1 and K2 provide redundant switching, while the monitoring connection allows the controlling safety relay to verify that both relays have returned to their safe state before a new ready signal is permitted.

Operating from a 24 V DC ±15% supply, the JSR1T 0 provides 4 NO safety outputs plus 1 NC information output, with resistive switching capacity up to 6 A at 250 V AC. Unlike the delayed versions in the JSR1T family, this model has a 0 s intentional delay, providing direct safety output deactivation for applications requiring an immediate stop signal.

Reliable Safety Output Expansion for Industrial Machinery

Safety expansion relays such as the ABB JSR1T 0 increase the number of available safety contacts without requiring separate independent safety functions for every controlled machine device. The JSR1T is connected to and monitored by a suitable safety relay, allowing multiple contactors, valves or other safety-related actuators to be controlled from the same safety system.

When inputs S14 and S24 are activated, the internal K1 and K2 relays energise and operate the safety outputs. Opening the inputs or removing the power supply causes both relays to drop out. Monitoring terminals X1 and X2 can be connected to the test or reset circuit of the controlling safety relay so that a new ready signal cannot be generated if an internal output contact fails to return to its safe state.

Typical Applications

• Expanding the outputs of industrial safety relays.
• Emergency-stop safety systems requiring additional outputs.
• Machine guard and interlock safety circuits.
• Control of multiple safety contactors.
• Safety-related valve and actuator control.
• Industrial machinery and automated production equipment.
• Manufacturing and material handling systems.
• Machine control panels requiring additional safety contacts.
