DIR-530
DIGITAL TANK DATA INDICATOR

GENERAL
Developed from the well accepted DIR-500, the RoHS compatible
DIR-530 is a panel mount type compact digital tank data indicator.
Connecting to any TOKYO KEISO's 2-wire digital tank data transmitters as well as tank top type servo operated tank gauges, DIR-530
serves for the following applications.
1. Dedicated receiving instrument for full time monitoring of one
tank
2. Inexpensive receiving instrument for moderate size tank farmwith a few tanks
3. Interfacing with supervisory system
At low cost, DIR-530 constitutes the simple, reliable, accurate digitalmonitoring and control system of the tank farm in combination withTOKYO KEISO's various tank monitoring 2-wire transmitters.

FEATURES❏ DIR-530 indicator receives signals from any TOKYO KEISO's 2wire digital tank data transmitters as well as tank top type servo
operated tank gauges.
❏ DIR-530 indicator provides two 4 -20mADC output signals andtwo alarm relay output signals when it is used as one tank monitoring.
❏ DIR-530 indicator is able to receive 4 transmitters which havesingle directional data transmission capability with 2-wire systemcommon to power and signal.
❏ DIR-530 indicator is able to receive 16 transmitters which have bidirectional data transmission capability, i.e. both from indicator totransmitter and vice versa, with 2 independent wirings of powerand signal.
❏ DIR-530 indicator is able to be connected to supervisory systems
such as personal computer, DCS and sequencer via pre-installed
serial and parallel communication ports, RS-232C or RS-485 with
Modbus-RTU.
❏ DIR-530 indicator is interchangeable with the current 1 tank receiver i.e. TOKYO KEISO's DIR-200 receiver and DIR-400 receiver, except alarm reset input of DIR-200. It makes your factory
renovation much easier.
❏ DIR-530 indicator indicates the operating status of itself as well as
level and temperature at the same time.
❏ DIR-530 indicator, its all operation parameters can be set frommenu selection through three key switches.
❏ DIR-530 indicator has the compact DIN 96 x 96 mm size to savepanel space.

Remote operation of displacer such as measuring, lifting, stoppage.

When multiple tanks are connected, automatic scanning isconducted and tank data on indication is updated with every
data entry.

Alarms are determined by comparing input signals and setting
values when signals enter. However, alarm indication is shown only
for the selected current tank. Alarm operation is of non-lock type.
Applicable only when FW-9000N is connected. Status ofdisplacer is shown on status and LED.
