Evaluation of incremental encoders with symmetrical push-pull outputs that cannot handle such high loads

Encoder supply +5 V

Connection for temperature sensor

ACOPOSmulti plug-in module, incremental encoder interface for 5 V single-ended and 5 V differential signals

Specifications

General information

Certifications – CE	Yes
Certifications – UKCA	Yes
Certifications – CRA (Cyber Resilience Act)	In preparation
Certifications – UL	cULus E225616; Power conversion equipment
Certifications – KC	Yes
Module type	ACOPOSmulti plug-in module
B&R ID code	0xA37E
Slot	Slots 1 and 2
Max. power consumption	P Module [mW] = 25 V * (I Encoder [mA] * 0.42 + 48 mA) (note: I Encoder ... Current consumption of the incremental encoder. The current consumption of the terminating resistors is already taken into account in the formula. A voltage drop on the encoder channel of max. 2x 1.5 V is also taken into account.)

Encoder connection

Electrical isolation – Encoder - ACOPOSmulti	Yes
Max. encoder cable length – Incremental encoders	25 m
Module-side connection	15-pin male DSUB connector
Status indicators	UP/DN LEDs

Encoder power supply 5 V

Sense lines – Quantity	2
Sense lines – Max. compensation	2x 1.5 V
Protective measures – Overload-proof	Yes
Protective measures – Short-circuit proof	Yes
Output voltage	5 V ±5%
Load capacity	350 mA (note: An additional reserve of 60 mA is available for terminating resistors.)

Inputs A, B, R

Single-ended signals – Input voltage for low	<1.0 V (against COM)
Single-ended signals – Input voltage for high	>2.4 V (against COM)
Single-ended signals – Maximum input voltage	-10 V / +13 V (against COM)
Differential signals – Differential voltage	±0.8 V to ±23 V (note: With open-circuit monitoring disabled, ±0.5 V is sufficient.)
Differential signals – Maximum input voltage	-10 V / +13 V (against COM)
Input resistance	See block diagram.

Incremental encoder operation
