IAC / IRC / CC insulation and phase sequence indicators, non-electrical quantity indicators, marine rpm and rudder position indicators, hour counters
Country: Spain · Model: IAC / IRC / CC / HC
A group of panel indicators for monitoring insulation and phase sequence, indicating process parameters, rpm and rudder position, and counting running hours. The housings follow IEC 61554, the test voltage is 2 kV, vibration and shock resistance follow VDE 0410, and a significant part of the instruments comes from the marine series.

Description
The IAC_V indicators measure the insulation resistance to earth in a three-phase network with an isolated neutral, and IAC_VA have an alarm with a continuously adjustable setpoint of 0–5 MΩ and an internal micro-relay. A selector switch in positions R, S or T identifies the faulty phase by the lowest reading; the frequency is 50–60 Hz and the accuracy ±1.5 % of the scale arc. IRC4E (72×72 mm) and IRC3E (96×96 mm) show the phase sequence in the 100–600 V AC range at a consumption of 1.2 VA. CC_V with a 90° scale and CC_C with a 240° scale, from 48×48 to 96×96 mm in size, display the signal of measuring transducers on inputs of 0–1, 0–5, 0–10, 1–5, 2–10 V or 0–1, 0–5, 0–10, 1–5, 0–20, 4–20 mA with an accuracy of 1.5 %. The rpm indicators CC4C, CC3C and CC2C are powered from a tacho-generator and have a 240° scale; the rudder indicator CCb8 (130×100 mm) works from a potentiometer on the rudder stock with a 40-0-40° or 45-0-45° scale and 12 V illumination. The hour counters HC5, HC4 and HC3 (48×48, 72×72 and 144×144 mm) have a mechanical 7-digit register, a tolerance of ±10 % Vn and a consumption of 10 mA.
How to choose
The type of instrument is determined by the quantity. For a network with an isolated neutral take IAC_V or IAC_VA with the alarm, and for phase sequence IRC3E or IRC4E depending on the cutout, 96×96 or 72×72 mm. For any signal from a transducer, CC_V or CC_C with a scale in your units will do. Engine rpm is shown by CC_C, and running time by HC3, HC4 or HC5.

FAQ
How is the faulty phase found with the IAC_V indicator?
The selector switch is turned to position R, S or T, and the faulty phase gives the lowest reading. Accuracy is ±1.5 % of the scale arc, frequency 50–60 Hz.
What inputs do the non-electrical quantity indicators have?
Voltage 0–1, 0–5, 0–10, 1–5, 2–10 V or current 0–1, 0–5, 0–10, 1–5, 0–20, 4–20 mA, accuracy 1.5 %.
What scales does the CCb8 rudder position indicator have?
40-0-40° or 45-0-45°, the port side is marked with a red arc and the starboard side with a green one, with 12 V illumination. The size is 130×100 mm.
Which standards and CE declarations apply to these instruments?
EN 60051, BS 89, EN 61010 and VDE 0410. CE declarations are available for IAC2VA, IRC3E/IRC4E and HC3–HC5.
