motrona Safety & Speed Monitors

Certified safety monitor for drive applications, with multifunctional inputs for HTL, RS422 and sine/cosine encoders plus an integrated signal splitter. Covers safety functions to EN 61800-5-2 such as SLS, SOS, SDI, SS1, SS2 and STO. Shown with the plug-in display and programming unit.

• SIL3 / PLe; 2 sin/cos, 2 RS422 and 2 HTL inputs up to 500 kHz
• Redundant relay, 4 redundant HTL outputs, safe 4–20 mA analogue output
• Set-up via USB software or plug-in BG230 unit; 18–30 VDC; DIN rail

Safety speed monitor for ramp, underspeed, overspeed, standstill and direction monitoring. Reaches SIL3 / PLe with two independent, non-certified sensors, so standard encoders can be used for safety tasks.

• Up to SIL3 / PLe with two standard sensors
• 2 pulse inputs (HTL / TTL-RS422) with signal splitter; 8 control inputs
• 4 transistor outputs (500 mA), 2 forced relays + 1 NO relay; USB set-up

The DS250 safety speed monitor with the optional BG200 operator unit attached. The BG200 snaps on magnetically, shows two-channel frequencies and scaled values on a bright OLED screen, and lets technicians set parameters on site without a PC.

• BG200: 1.54" OLED (128 x 64), six touch keys
• Fits DS230, DS240, DS250 and DS260 safety monitors
• Magnetic mounting, 8-pin connector, powered by the host unit

Universal monitors for overspeed, underspeed, standstill and direction of rotation from incremental encoders and sensors. A backlit LCD and four keys allow direct set-up; variants offer relay, transistor and analogue outputs.

• Inputs HTL (A, B) or RS422 (A, /A, B, /B), up to 1 MHz
• 3 relay outputs; DZ260 adds a 14-bit analogue output
• Backlit LCD and keypad; RS232 PC set-up; 17–30 VDC; DIN rail

Simple, compact monitor that detects direction of rotation and standstill from incremental encoders and sensors with HTL, RS422 or TTL outputs. Set-up by DIP switches, so no software is needed.

• Relay 1: direction; relay 2: direction or standstill
• 2 fast transistor outputs; response < 1 ms
• Up to 500 kHz (RS422/TTL); 17–30 VDC; 5.4 V encoder supply

Powerful successor to the DZ260 series for incremental encoders, SSI absolute encoders and start-stop displacement transducers. Measures frequency or position and switches four control outputs, with a 16-bit analogue output for control tasks.

• HTL / TTL / RS422 inputs up to 1 MHz; SSI master or slave, 10–32 bit
• 4 control outputs; 16-bit analogue ±10 V or 0/4–20 mA
• DZ220/RL variant with 4 relays; 18–30 VDC; DIN rail
