| | MM-TA-12B Muting Module Specifications (cont'd) | |
| | Inputs | The MSSI and the USSI can be interfaced with external safety devices that have either hard contact outputs or solid-state OSSD safety outputs with Safety Handshake protocol. Maximum external resistance must not exceed 1000 C per channel. Operating Range for MSSI and USSI Inputs OFF State: 0-3V, 0-2 mA ON State: 12-30V, 10-50 mA Muteable Safety Stop Interface (MSSI) This input consists of two channels (MSSI-A and MSSI-B), and can be muted when the requirements for a mute cycle have been met. When muted, the OSSDs remain ON, independent of the MSSI status. If not muted, when one or both channels open, the OSSD outputs will go OFF. Universal Safety Stop Interface (USSI) This input consists of two channels (USSI-A and USSI-B), and is always active. When one or both channels open, the OSSD Outputs will go OFF. | |
| | External Device Monitoring (EDM) | Two pairs of terminals are provided to monitor the state of external devices controlled by the OSSD outputs. Each device must be capable of switching 15-30V dc at 10-50 mA. | |
| | Muting Device Inputs | The muting devices work in pairs (M1 and M2, M3 and M4) and are required to be "closed" within 3 seconds of each other (simultaneity requirement) to initiate a mute (assuming all other conditions are met). Sensor connected to M1 (and M3) must have contacts or PNP output. Sensor connected to M2 (and M4) must have contacts or NPN output. Each muting device must be capable of switching 15-30V dc at 10-50 mA. | |
| | Mute Enable Input | When Mute Enable is selected (functional), this input must have +24V dc applied in order to start a mute; opening this input after mute has begun has no effect. If Mute Enable is disabled, this input will be ignored and a mute cycle can occur regardless of the state of the mute enable input. The switching device must be capable of switching 15-30V dc at 10-50 mA. | |
| | Override Inputs | The two-channel inputs must be closed within 3 seconds of each other (simultaneity requirement) and held closed during the 10-second Override. To initiate a subsequent Override, open both channels, wait 3 seconds, and then re-close both channels (within 3 seconds). The switching devices must be capable of switching 15-30V dc at 10-50 mA. | |
| | Reset Input | Terminals must be closed for a minimum of 0.25 seconds and not more than 2.0 seconds in order to guarantee a reset. The switching device must be capable of switching 15-30V dc at 10-50 mA. | |
| | Mounting | 4 mounting holes, 5.5 mm dia. | |
