Professional FAQ
Q: Can I switch both AC and DC loads with the TM3DQ16R?
A: Yes. The relay contacts support 5–30 Vdc and 5–250 Vac. This makes the module useful for mixed panels. Always check the load current. Keep each channel at or below 2 A. Keep each common line at or below 7 A.
Q: How do I choose between the TM3DQ16R and a transistor output module?
A: Choose the relay version for AC loads or mixed voltages. Choose a transistor module for fast switching and long cycle life. The TM3DQ16R uses mechanical relays. It is better for lower switching rates and flexible load types.
Q: What should I check before installing this module in an existing M241 panel?
A: Check bus compatibility, panel space, and wiring clearance. The module is 27.4 mm wide. Confirm the 24 Vdc bus supply. Also check the 7 A common line limit. Review the existing output loads before you wire the module.
Q: Does the TM3DQ16R provide short-circuit protection?
A: No. It is a relay output module. It provides module status and bus status diagnostics. It does not provide electronic short-circuit protection. Add external fuses or breakers for load protection.
Q: How fast can I expect delivery, and what warranty applies?
A: Oiltech Controls dispatches in 24–28 hours. We ship by FedEx, UPS, and DHL. Every unit carries a 12-month warranty. We also verify the module before shipment. Contact us for stock and lead time.
