Instruction Manual
Components and Specifications
2.1 Specifications, continued
*Contact the factory for IEC 61508/62061 and ISO 13849-1 data. Specifications continued on page 11.
Inputs The MSSI and the SSI can be interfaced with external devices that have either hard contact
outputs or solid state sourcing outputs.
When connecting the MSSI (S11–S12, S21–S22) or SSI (X5–X6, X7–X8) inputs to relay outputs
or hard contacts, these contacts must be capable of switching 15–30V dc at 10–50 mA.
Operating Range for MSSI and SSI Inputs
OFF State: -3V to +5V, 0 to 2 mA
ON State: 15–30V, 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, anytime either or both channels open, the OSSD outputs will go
OFF. Maximum external resistance per channel must not exceed 400 Ω. (See Section 3.5.6 for
further information.)
Safety Stop Interface (SSI)
This input consists of two channels (SSI-A and SSI-B), and is always active. Any time either or
both channels open, the OSSD Outputs will go OFF. Maximum external resistance per channel
must not exceed 400 Ω. (See Section 3.5.6 for further information.)
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/synchronous actuation) to initiate a
mute (assuming all other conditions are met). Each muting device must be capable of switching
15–30V dc at 10–50 mA.
Mute Enable Input The Mute Enable input must have +24V dc applied in order to start a mute; opening this input after
mute has begun has no effect. 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/synchronous
action requirement) and held closed during the 30-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 Mounts to standard 35 mm DIN-rail track.
Vibration Resistance 10 to 55 Hz @ 0.35 mm displacement per IEC 68-2-6.
Construction Polycarbonate housing. See Section 2.3 for dimensions.
Environmental Rating Rated NEMA 1; IEC IP20. Safety Module must be installed inside an enclosure rated NEMA 3
(IEC IP54) or better.
Connections Removable terminal blocks; see Figure 3-4 for terminal locations.
Operating Conditions Temperature range: 0° to +50° C (+32° to 122° F)
Max. Relative Humidity: 95% (non-condensing)
Heat Dissipation Considerations: See Section 3.2 “Installing the Module”.
