The CT6S-1P4 is a programmable counter or timer in one enclosed 1/16 DIN unit. It contains a selectable voltage, no-voltage or contact input connection and single pole double throw (1c) contact and one solid state output. The CT series allows up to six digit pre-scale settings to provide the user with flexibility in a variety of application environments. Also, the LED display is a 7-segment character design with the process/counting value in red (10 mm height) and setting value in green (7 mm height); the decimal point position is selectable as well. In addition, the CT series has the capability, with the use of a USB headphone style plug adapter, to allow parameter and setting values to be programmed with a PC or PLC via free software provided by Autonics.
