It features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and an optimal control behavior.

The well-proven I/P module proportionally converts the permanent electrical positioning signal from the CPU into a pneumatic signal used to adjust a 3/3-way valve. The air flow for pressurizing or depressurizing the actuator is continuously adjusted. As a result, excellent control is achieved. When reaching the set point, the 3/3-way valve is closed in center position to minimize the air consumption. Four different pneumatics versions are available: for single-acting or double-acting actuators, each with “fail-safe” or “fail-freeze” function.

Travel limit The positioning travel, i.e. the stroke or angle of rotation, can be reduced as required within the full range of 0 ... 100 %, provided that a minimum value of 20 % is observed. Shut-off function This parameter can be set separately for each end position. When the respective configured limit value is exceeded, the shut-off function causes immediate travel of the actuator until reaching the set end position. When the shut-off value is set to “0”, the position is further controlled, even in the respective end position. Travel time prolongation This function can be used to increase the max. travel time for full travel. This time parameter can be set separately for each direction. Important This function can only be used with the pneumatics with the safety function “fail-safe”. Switching points for the position This parameter allows you to define two position limits for signaling (see option “Module for digital position feedback”). Digital output The alarms generated in the TZIDC positioner can be polled via the digital output as a collective alarm. The desired information can be selected via the operator panel or remotely via the configuration program. The output can be set to “active high” or “active low”, as required. Digital input For the digital input, one of the following safety options can be selected. You may use the operator’s panel or configuration program to select an option. - No function (default) - Move to 0 % position - Move to 100 % position - Hold previous position - disable local configuration - Disable local configuration and operation - Disable any access (no local or remote access via a PC) The selected function is activated once the 24 V DC signal is no longer applied (< 11 V DC).

This allows you to work with the same user interface in the commissioning phase, during operation, and for service tasks for monitoring the device, setting parameters, and uploading data. Communication is based on the HART protocol. It occurs via a local interface connection (LKS) or in frequency-modulated mode using an FSK-modem connected at any chosen point of the 20 mA signal line. Communication has no effect on operation. Newly set parameters are saved in the non-volatile memory directly upon the download into the device, and become active immediately.
