DS246: Certified Safety Monitors with SinCos Encoder without Signal Splitter

The DS246 is discontinued as of 31.12.2025. We recommend the DS240 as an alternative. More details about the DS240 ...

The devices of the DS240 - 246 series are designed for the connection of a SIL3/PLe certified sine cosine encoder or sensor. The DS246 is equipped with a relay, 4 transistor outputs and an analog output, but has no signal distributor (in contrast to the DS240).

Safety functions equivalent to EN 61800-5-2
(SS1, SS2, SOS, SLS, SDl, SSM, SLI, SBC, STO, SMS)
1 encoder input with format SIN+, SIN-, COS+, COS- [1 Vss]
2 pulse inputs with format A, /A, B, /B [RS422]
2 pulse- or control inputs with format A, B, 90°
[HTL / PNP] (for rotary encoder, proximity switches or commands)
Input frequency up to 500 kHz
Forced-guided redundant output relay (NO)
4 control outputs with push-pull characteristic, short-circuit-proof,
[HTL], each inverse and redundant
Safety related 14 bit analog output for 4 ... 20 mA (scalable)
Power supply 18 ... 30 V
Compact housing for 35 mm mounting top hat rail
(according to EN 60715)
Setup via USB port by operator software or plug-in display and
programming unit BG230 (accessories)
