SA-BM Base Module
Base Module Data
SA-BM-S1
Master base module
The SA-BM master base module is the obligatory
module of the
samos
system. On its own it functions
as a complete safety switching device for monitoring
up to 2 safety circuits.

The controller category (EN ISO 13849-1) or SIL (EN 61508/EN 62061) depends on the
external circuitry, the wiring, the choice of control devices and their location on the
machine.
In the event of single-channel control of a contact extension (e.g. SA-OR) through a base
module (SA-BM), category 4 according to EN ISO 13849-1 can be achieved if both
devices are installed in the same enclosure.
The SA-BM must be protected with a 6 A fuse of utilization category gG or a 6 A (4 A)
circuit-breaker (tripping characteristic B or C).
The rotary switches for selecting function and time must only be adjusted when power is
off.
Never connect or disconnect modules while the operating voltage is switched on.
If external contactors or relays are connected, the feedback circuits (NC contacts) must
be connected to the base module.
When inductive loads are connected (e.g. valves, contactors) a suppressor circuit must
be set up (e.g. RC combination).
Internal
samos
module addresses are assigned automatically when the system starts up.
Manual addressing is unnecessary (and not possible).
The safety system must be installed in an enclosure with at least IP 54 protection.
Each base module forms a system group within the overall system (sometimes together
with associated input expansion modules; see diagram on page 8).
