Description
Trumeter M2 Signal Conditioner for Mains-Powered Multi-Function Monitoring
The Trumeter M2 (SC-M2-DIN) is the mains-powered sibling to the M1, measuring current, voltage, or frequency from a single DIN rail-mount housing. It runs directly from a 100-240V AC supply, so it drops into a panel without needing a separate low-voltage transformer or power supply. As a result, it suits retrofits where a spare 12-24V feed is not available.
- 3-in-1 input: current (0-5A direct or up to 10,000A via CT), voltage (0-600V AC/DC), or frequency (2-400Hz)
- Mains powered: 100-240V AC, 50-60Hz, no external PSU required
- Two configurable outputs: digital (open collector) or analog (4-20mA)
- 1.0% measurement accuracy
- 10 alarm setpoints with configurable digital output delays
Because the M2 takes its power straight from mains, installers save the cost and panel space of a separate 12-24V supply. For example, use it on a switchboard or distribution panel where mains is already present but a low-voltage rail is not. It is also cloud-ready, connecting to Trumeter Cloud via the optional IoT Gateway for remote monitoring.
Configuration and Installation
The M2 clips onto standard Top Hat Slotted (TS35) DIN rail and measures 72mm x 72mm x 61mm, matching the M1’s footprint so the two can be mixed in the same enclosure. Configuration runs through Trumeter’s free software over USB, with 20-point non-linearization scaling available for non-linear sensors. Therefore, one stocked unit can be configured on-site for the required input, range, and alarm behaviour.
The unit carries CE, cUL, UL, RoHS, and IP20 ratings, covering most industrial and OEM panel-building requirements without extra certification paperwork.
