Key features
- Modern, multilingual touchscreen HMI — intuitive configuration, operation and fault diagnostics.
- SmartStart function — guided configuration during system commissioning, saving programming time.
- Automatic EZ-ID detector recognition — supports the MSA and General Monitors HART detector library.
- Up to 6 discrete inputs assignable by the user and up to 56 relays.
- 3 common relays: fault, alarm, panel horn.
- Wall-mount versions in 8- or 16-point configurations.
- Multiple communication interfaces: Modbus TCP/IP, EtherNet/IP, optional Modbus RTU.
- Advanced control logic — cause & effect functions and voting schemes.
- Device Level Ring (DLR) topology — savings in wiring cost and time on projects.
- Ability to network multiple SENTRY io controllers — savings in new and existing installations.

Frequently asked questions (FAQ)
What is the EZ-ID function?
It is automatic recognition of connected HART detectors from MSA and General Monitors, which significantly reduces system configuration time.
How many measurement points does SENTRY io support?
The controller is available in 8- or 16-point versions, with an option for up to 56 relays and 8 or 16 analog outputs respectively.
Can SENTRY io controllers be networked?
Yes — thanks to the Device Level Ring (DLR) topology, multiple SENTRY io units can be connected into a single communication loop, reducing wiring cost and complexity.
