  • Datasheet

The VisiPak model V434 is a versatile, field configurable, bridge and strain gage input LED indicator which provides a NEMA 4X water tight front panel that fits 1/8 DIN cutouts. The four visual setpoint alarms are standard and annunciated via individual front panel LEDs. Programmable tare and peak hold functions are incorporated for weight and pressure measurement applications.

Two form C relays are available as optional outputs for the first two setpoints. They can be configured as high or low, failsafe or non-failsafe. Each setpoint has a 100% adjustable deadband (or reset points) which can be effectively used in on/off control applications or as a latching alarm. An isolated 4-20mA transmitter output is also available as an option, with or without the two relays.

The V434 accepts 0-30mV, 0-200mV, +15mV, and + 100mV inputs. It displays any engineering scale required, between 501 and + 199990 counts for the full-scale span, including a programmable decimal point. There is an isolated, field configurable 5V, 10V or 24V excitation source to power a bridge or strain gage, or the optional two-wire transmitter output.

Field configuration of the input range, alarm function, and analog transmitter output scaling is quick and easy since only one button is required to toggle through the selections. The indicator is factory calibrated to rated accuracy but can be checked and adjusted in the field if necessary, using the same configuration button.

The programmable tare function can accept a measured value by pressing the TARE button or a tare value can be input through the display using the ENTER button. Terminals are provided for remote alarm acknowledgment which can be used to unlatch or reset an alarm when it is within the deadband portion of the setpoint alarm range.

To prevent tampering and ensure safety, a lockout jumper is used to limit access to the configuration button functions. When the lockout mode is enabled, only tare, peak, alarm setpoints and output scaling functions are displayed and they can not be altered without moving the lock jumper, except for tare.
