The EL9550 system terminal contains an overvoltage filter for the 24 V field and system supply. The filter protects the EtherCAT Terminal from line-bound surge voltages that can occur due to high-energy, dynamic disturbances such as switching overvoltages at inductive consumers or indirect lightning strikes at the supply lines.
The EL9187 potential distribution terminal provides 8 terminal points with the 0 V potential at the front on the terminal contacts. The 0 V power contact is connected to the front-side terminal contacts and is passed through to the adjacent terminal.
The KL1002 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains two channels that indicate their signal state by means of light emitting diodes.
The KL1154 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains four channels that indicate its signal state by means of light emitting diodes.
The KL1312 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal has two channels, whose signal state is displayed by light emitting diodes.
The digital KL1362 input terminal analyzes the input signals of break-in sensors with the aid of a current loop. It enables safe monitoring of alarm contacts with fixed resistance ratio. In addition to the display of the switching state from the sensor, short circuit or open circuit is also detected. The LEDs display the signal states or any error states.
The KL1382 digital input terminal analyzes the input signal from thermistor sensors with the aid of a current loop and a voltage of < 5 V. The bus terminal has two channels.
The KL1402 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains two channels that indicate its signal state by means of light emitting diodes.
The KL1488 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit.
Special features: suitable for fast counting tasks with counting frequencies up to 100 kHz an up counter and a down counter, or two separate up or down counters
