MM-TA-12B Muting Module Specifications

Supply Voltage and Current +24V dc ±15% @ 400 mA max (not including draw of the MSSI power, AUX, ML, M1-M4 and OSSD connections)
SAFETY MODULES PICO-GUARDCONTROLLERS Supply Protection Circuitry All inputs and outputs are protected from short circuit to +24V dc or dc common. Output Response Time Muteable Safety Stop Interfaces (MSSI) and the Universal Safety Stop Interfaces (USSI) are less than or equal to 10 milliseconds.
E-STOP/GUARDMONITORING Safety OutputsTwo diverse-redundant solid-state safety outputs: 24V dc, 0.5A sourcing OSSD (output signal switching device). Compatible with Banner “Safety Handshake” protocol.
SAFETY MATMONITORING ON-State voltage: ≥ V in-1.5V dc
MUTINGMODULES Max. leakage current: 1.2 mA; inclusive of faults (including open 0V dc wire) OFF-State voltage: 1.2V dc max.
EXTENSIONMODULES Max. load capacitance: 0.1 µF Non-safety auxiliary output: PNP solid-state output, rated at +24V dc @ 250 mA.
INTERFACEMODULES OSSD test pulse width: 100 to 300 microseconds OSSD test pulse period: 12 microseconds MSSI Power connections +24V dc ±15% @ 2.5A max. output (dependent on System power input). Resettable 2.5A industrial fuse Status Indicators3 Status Indicator LEDs (Red, Green and Yellow): indicate Power ON/OFF, operating mode, lockout, override, and OSSD status Green LEDs adjacent to individual inputs/interfaces indicate status (ON = active/closed) Diagnostic Code Display Diagnostic Display is a two-digit numeric display that indicates the cause of lockout conditions and the amount of time, in seconds, remaining for the backdoor timer. Muting Lamp Output A monitored or non-monitored (selectable) sinking output. If monitoring has been selected, the current draw must be 10 mA to 360 mA. Interconnect wire resistance < 30 . Max. switching voltage: 30V dc Max. switching current: 360 mA Min. switching current: 10 mA Saturation voltage: ≤ 1.5V dc @ 10 mA; ≤ 5V dc @ 360 mA Controls and AdjustmentsAll configured on two redundant banks of DIP switches: Manual/auto reset One-way/two-way muting Monitored/non-monitored mute lamp output One-channel/two-channel/no EDM Backdoor timer Mute on power-up enable Mute enable functional/disabled
