Banner Engineering MMD-TA-11B Safety Relay Muting Module Controller

The Banner Engineering MMD-TA-11B Muting Module Controller is a 24 V DC safety-relay muting module designed to suspend safeguarding during hazard-free times, enabling material to move into or from the process without tripping the primary safety device. It provides two NO safety outputs rated at 6 A and a single auxiliary NC output rated 0.25 A, plus one muteable safety input and one non-muteable safety input (both dual‑channel) and auto/manual reset, with self‑checking circuitry and external device monitoring (EDM) to improve reliability. The unit’s compact DIN‑rail footprint measures 84 mm high by 67.5 mm wide by 118 mm deep, uses a removable terminal block, and carries an IP20 rating for typical machine environments; it operates from 24 V DC and supports input configurations including 2 NC, 1 NC, or 2 PNP depending on model, along with muting functionality via M1–M4 mute inputs and a mute enable input (ME). As part of Banner’s MMD series, the MMD‑TA‑11B is designed for safeguarding systems requiring controlled muting of the safety stop signaling while preserving fail-safe behavior, and is available in variants for DIN‑rail mounting or IP65‑rated flat‑mount housings to suit different installation needs.
