Model Numbers
DS 240 | 1 relay, 4 control outputs push-pull, analogue output, signal splitter |
DS 246 | 1 relay, 4 control outputs push-pul, analogue output |
BG 230 | Display and programming module (optional) |
Features
- SIL3 and PLe certification
- Safety functions equivalent to EN61800-5-2 (SS1, SS2, SOS, SLS, SDI, SSM)
- Suitable for the connection with SIL3/PLe certificated Sin-Cosine sensors or SinCos encoders with 1 Vpp
- Two inverse redundant HTL/PNP inputs for encoders, proximity switches and control commands
- Extremely large bandwidth of 500 kHz
- Forced guided redundant output relay (NO). Beside device errors, more alarm states can freely be parameterized
- The function of the four inverse redundant digital outputs is also free programmable
- Safe analogue output with 4 - 20 mA for transmitting of proportional control loop values.
- Easy and safe integration into existing sensor wirings enabled by the integrated signal splitter
- Fast and intuitive parameter setup by using the free service software or by using the programming module
- Snap-on module for stndard DIN rails (35mm C-profile)
