MMD-TA-11B / MMD-TA-12B Muting Module
Instruction Manual
Components and Specifications
Non-Safety Outputs Model MMD-TA-11B:
Aux. output 31–32 is a parallel connection of two N.C. contacts from internal relays K1 and K2.
Contact: AgNi, 5 µm gold-plated
Low Current Rating:
Caution: The 5 µm gold-plated contacts allow the switching of low current/low voltage. To
preserve the gold plating on the contacts and also guarantee reliable switching, the following values
should be kept within the min. and max. ranges shown below:
Min. Voltage: 1V ac/dc Max. Voltage: 24V ac/dc
Min. Current: 5 mA ac/dc Max. Current: 250 mA ac/dc
Min. Power: 5 mW (5 mVA) Max. Power: 6 W (6VA)
High Current Rating:
For higher loads, the min. and max. values of the contact(s) changes to:
Min. Voltage: 15V ac/dc Max. Voltage: 24V ac/dc
Min. Current: 30 mA ac/dc Max. Current: 250 mA ac/dc
Min. Power: 0.45 W (0.45VA) Max. Power: 6 W (6VA)
Mechanical Life: 50,000,000 operations
Electrical Life: >10 x 10
6
cycles
Model MMD-TA-12B:
Z4–Z3 = Aux. 24V / 250 mA PNP output follows the two OSSD safety outputs.
Status Indicator LEDs 3 Status Indicator LEDs (Red, Green and Yellow): indicate waiting for Reset, Lockout,
Override, and OSSD status
Yellow and 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 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 ohms.
Maximum Switching Voltage: 30V dc
Maximum Switching Current: 360 mA
Minimum Switching Current: 10 mA
Saturation Voltage: ≤ 1.5V dc @ 10 mA; ≤ 5V dc @ 360 mA
Controls and Adjustments All configured on 2 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
