Safety Mat Controllers

ZM3008 Controller

The Zone Monitor 3008’s simple design technology enables it to withstand the toughest industrial environments, while still providing the advanced diagnostics and reliable performance you demand. The Zone Monitor accepts up to eight safety mats without junction boxes, accommodating larger mat layouts efficiently.

Available with or without quick disconnect wiring plug receptacles installed and wired (ZM3008QD). Safety mats ordered the optional the four-wire molded plug cord quickly connect to the receptacles making installation fast.

ZM3000 Controller

The Zone Monitor 3000 Safety Mat Control Unit offers a sophisticated mix of advanced mat system monitoring and simple dependability. Designed for the toughest industrial environments, the Zone Monitor 3000 provides individual mat status indicators for up to four Larco safety mats through high-visibility LEDs. In addition, the Zone Monitor 3000 can accommodate a variety of power requirements and is designed to meet or exceed CE, UL, and CUL safety system requirements.

Available with or without quick disconnect wiring plug receptacles installed and wired (ZM3000QD). Safety mats ordered the optional the four-wire molded plug cord quickly connect to the receptacles making installation fast.

MAX-Series Controller

The Larco MAX-Series control units are designed to provide continuous safety system monitoring in applications where individual mat diagnostics are not necessary. The MAX's four-wire closed loop mat circuit is designed to monitor safety mats for activation. Larco MAX-Series is capable of monitoring up to ten safety mats when used with a junction box or terminal strip.

In addition, the MAX can accommodate automatic restart and guard only modes and three different input voltages.
