Overview
The Banner IM-T-9A interface module is a safety relay designed to expand the switching capability of low-voltage primary safety devices such as safety light curtains and safety scanners with external device monitoring (EDM) functionality. This relay module increases the output switching current capacity to 6 amps, enabling safe control of higher-load safety circuits while maintaining forced-guided contact architecture for failure detection.
Key Features
- Three normally open (3NO) redundant output channels — each rated for 250V ac/dc at 6 amps
- 24V dc supply voltage with ±15% tolerance; 100 mA rated supply current
- Forced-guided (mechanically-linked) contacts — allows primary safety device to detect module failures
- 20 millisecond response time — output relay contacts open within 20 ms of safety input opening
- Dual green status LEDs — indicate output status of internal relays K1 and K2
- Removable terminal blocks — simplifies installation and maintenance
- DIN rail mounting — compact 22.5 mm width for standard cabinet installation
- Safety Category 4 / PL Rating e / SIL 3 — meets ISO 13849-1 and functional safety standards

Compatibility & Replacements
Compatible With
- Banner safety light curtains and safety scanners with OSSD or hard contact outputs
- Banner EZ-SCREEN and equivalent safety devices with EDM (external device monitoring) capability
- Primary safety modules and controls with solid-state or relay outputs
- Standard 24V dc safety control systems and industrial control circuits
- DIN rail-mounted control enclosures and safety relay cabinets
Replaces / Drop-In Replacement For
- Verify specific replacement compatibility with your original equipment documentation; the IM-T-9A is not a stand-alone safeguarding device and must be paired with a primary safety device.
Works With
