Why Choose the ABB SENTRY SSR10M 2TLA010050R0100 Safety Relay?
The ABB SENTRY SSR10M 2TLA010050R0100 is a compact industrial safety relay with a wide-range AC/DC power supply, designed for monitoring safety-related circuits in machinery and automation systems. Part of the ABB Jokab Safety Sentry range, the SSR10M is intended for safety devices using two equivalent contact channels, making it suitable for applications such as emergency stops, guard switches and safety output expansion.
The SSR10M provides 3 normally open failsafe relay outputs and 1 normally closed relay output, providing multiple switching contacts for contactors and other machine control equipment. Manual or automatic reset can be selected using the switch on the front of the relay, allowing straightforward configuration to suit different machine safety requirements.
A key advantage of the SSR10M is its wide operating supply range of 85–265 V AC at 50/60 Hz or 120–375 V DC. This allows the same safety relay to be integrated into systems using common mains-level AC or high-voltage DC control supplies, while its compact 22.5 mm wide enclosure and detachable screw connection blocks provide space-efficient DIN-rail installation.

Wide-Voltage Safety Monitoring for Industrial Machinery
Safety relays such as the ABB SENTRY SSR10M provide a monitored interface between machine safety devices and the equipment responsible for removing hazardous movement or energy. The SSR10M is specifically intended for safety devices using two equivalent contact channels, allowing redundant emergency-stop buttons, guard switches and similar contact-based devices to be monitored as part of the machine safety circuit.
The SSR10M's wide 85–265 V AC / 120–375 V DC supply range is particularly useful when a 24 V DC control supply is unavailable or where existing machinery operates with higher control voltages. Its 3 NO failsafe outputs provide multiple switching paths for machine contactors or other safety-related equipment, while selectable manual or automatic reset enables the relay to be configured for different operating requirements.
Typical Applications
- Emergency-stop monitoring.
- Interlocked machine guards, gates and hatches.
- Safety switches with two equivalent contact channels.
- Safe output expansion.
- Machinery using 115 V AC or 230 V AC control supplies.
- Industrial machinery and automated production equipment.
- Manufacturing and material handling systems.
- Machine control panels requiring a wide-range AC/DC safety relay.
