Why Choose the ABB 2TLA010050R0101 Sentry SSR10MP Safety Relay?
The ABB 2TLA010050R0101, model Sentry SSR10MP, is a compact safety relay designed for monitoring safety devices with two equivalent contact channels. It combines a wide-range 85–265 V AC / 120–375 V DC power supply with 3 normally open safety relay outputs and 1 normally closed auxiliary output, making it suitable for industrial machinery where a higher-voltage control supply is available.
The SSR10MP supports common contact-based safety functions including emergency-stop and safety gate monitoring. Manual or automatic reset can be selected using the switch on the front of the relay, providing flexibility for different machine restart strategies without requiring a different relay model.
This MP variant combines the Sentry SSR10 monitoring functionality with the wide-range AC/DC supply and detachable push-in spring connection blocks. Its narrow 22.5 mm DIN-rail housing, IP20 protection and safety capability up to PL e / SIL 3 make it a versatile choice for safety-related control panels and machine-building applications.

Reliable Two-Channel Safety Monitoring
The Sentry SSR10MP monitors safety devices equipped with two equivalent contact channels, providing redundant input monitoring for applications such as emergency-stop buttons and mechanically operated safety gate switches. Its three normally open failsafe contacts can be incorporated into the machine's safety-related control system, while the additional normally closed contact provides an auxiliary switching function.
The selectable manual or automatic reset allows the relay's restart behaviour to be matched to the machine application. Combined with the wide-range AC/DC power supply and push-in connection technology, this makes the SSR10MP especially useful where designers require a conventional contact-monitoring safety relay without depending on a 24 V DC control supply.
Typical Applications
- Emergency-stop monitoring circuits.
- Safety gate and guard-switch monitoring.
- Two-channel contact-based safety devices.
- Machine shutdown and isolation functions.
- Safety-related contactor control.
- Industrial machinery with higher-voltage AC or DC control supplies.
- Conveyor and material-handling equipment.
- Packaging and processing machinery.
- Automated production and assembly systems.
- OEM machine control panels requiring a compact safety relay.
