Product Overview
The Schneider Electric SR2B201BD is a
Zelio Logic SR2 compact smart relay with
20 digital I/O points: 12 DC inputs
and 8 normally open relay outputs. Among its twelve
input terminals, six can also be configured for 0–10 V or
0–24 V analog voltage signals (8-bit resolution); these
are shared terminals, not six additional I/O points. The controller
operates on a 24 V DC supply and includes an
integrated clock and local display. It supports
Ladder Logic and FBD programming, with up to
120 Ladder or 200 FBD control scheme lines. Schneider's datasheet
gives an 8 A relay thermal rating, while its wiring diagram
specifies 5 A maximum at Q9 and QA and 10 A at
common terminal C. Check the exact model, input function assignments,
relay wiring and load categories before ordering.
