The MTL 8215-DO-IS is a 4-channel intrinsically safe discrete output module with dedicated solenoid drivers for IIC gas groups. It energizes solenoid valves, alarms, and small actuators located in explosive atmospheres, delivering certified IS output circuits directly from the MTL 8000 remote I/O rack without external barriers.

FAQ
Q: What loads can each channel drive? A: Each channel drives one IS-rated solenoid or equivalent load within the 45 mA current limit.
Q: Can it be used in IIA or IIB areas? A: Yes, IIC certification covers all lower gas groups including IIA and IIB.
Q: Which field terminal pairs with this module? A: The 8621/8624-FT-IS intrinsically safe field terminals per the MTL wiring diagram.
Installation Guide
Confirm the solenoid ratings fall within the module output parameters and certificate.
Insert the module into the rack and verify the key code B5 alignment.
Connect field solenoids via the certified IS field terminal, observing polarity.
Command each channel from the host and measure output voltage under load.
Record loop parameters in the IS schedule and close out commissioning documentation.
Selection Tips
Verify solenoid inrush and holding currents against the 45 mA channel limit before ordering.
For higher channel counts, combine multiple 8215-DO-IS modules on one rack.
Select non-IS DO modules for safe-area solenoids to reduce cost.
Match field terminal selection to loop-disconnect requirements for maintenance.
