Growlink 4 Triac Out Module

4-Channel Triac Output Module for Fast-Cycling Dosing Loads The BMT-F-TO4 carries four solid-state triac outputs rated 0.8 A each at 24 V AC/DC. Where a DO-4 relay would burn out chasing the rapid pulses an HE Anderson injection pump asks for, the triac switches stay clean. The pump fires rhythmically at the injection rate the dosing recipe calls for, and BACnet MS/TP carries the setpoints from the Growlink controller. BACnet MS/TP Triac Module with Manual Override on Every Channel Each output gets a three-position black toggle. Setting A lets Growlink software command the channel. Setting 1 forces the triac on. Setting 0 locks it off. The module clips to a TH35 DIN rail and lands the BACnet line on spring-clamp terminals, so commissioning takes minutes per panel. Wire it next to a BMT-F-DI4 or BMT-F-AOP4 for a full BACnet I/O stack on the same trunk. Key Features 4 triac outputs at 0.8 A: Solid-state switching for fast-cycling AC loads like HE Anderson dosing pumps and small solenoid valves. BACnet MS/TP communication: Plugs into the Growlink controller and any other BACnet trunk without protocol gateways. Manual A/1/0 toggle per channel: Switch from software control to forced on or forced off without rewiring the panel. 24 V AC/DC supply: Pairs with the same low-voltage bus that runs the rest of the BMT-F I/O lineup. TH35 DIN rail mount: Spring-clamp terminals snap into IEC 60715 rail for clean panel build-outs. No mechanical relays to wear out: Triac switching handles the rapid pulse trains a relay would burn out on inside a season. Stackable with BMT-F-DI4 / BMT-F-AOP4 / BMT-F-RTR: Build a full BACnet MS/TP I/O bank on one trunk with the Metz Connect family.
