Models 8501 and 8502 converters contain two independent channels, which accept a TTL or 24 V pulse signal, and convert that signal to a 24 V pulse or TTL output. This is useful in a stepper motor to PLC interface when only a 24 Vdc to 5 kHz signal is available, and the receiving device requires a 5 V TTL input. They are housed in a DIN-rail-mount enclosure and are recognized by UL 508 and 1604.
