Selection of input modules according to measurement requirements...

TC/DC amp (AP11-107)
This amp can be used as a thermocouple amp or DC amp. When temperature measurement using a thermocouple amp and voltage measurement using a DC amp are necessary, this amp is useful because no amp replacement is required. Moreover, four types of thermocouples, R, T, J, and K, can be connected and high-speed temperature measurement as fast as 10 µs is possible. This amp contains one channel per unit.

Event amp (AP11-105)
This amp is a logic amplifier that can input eight channels of voltage or contact signals. It is useful for measuring timing or contact signals.
Voltage input: Input voltage 0 to 24 V
H level: 2.5 V or higher
L level: 0.5 V or lower
Contact input:
Open: 2 k or higher
Short: 250 or lower

2-ch AC strain amp (AP11-104)
This amp is a 2-channel amplifier that inputs signals from strain gauges or strain gauge based sensors. Due to the AC bridge type, it features high noise resistance(against the noise caused by the line voltage), high stability, and a high resolution of 16 bits. Low-noise measurement is possible for measurement using strain gauges, which do not have any shielded wires.
Auto-balance
Bridge voltage: 5 kHz, 2 V rms
Response frequency: 0 to 2 kHz
Gauge factor adjustment function: 1.9 to 2.2

2-ch DC strain amp (AP11-110)
This amp is a 2-channel amplifier that inputs signals from strain gauges or strain gauge based sensors. Due to the DC bridge type, it features measurement of high-speed strain signals at a high resolution of 16 bits.
Auto-balance
Bridge voltage: 2 VDC, 5 VDC

2-ch vibration/RMS amp (AP11-109)
This is a 2-channel amplifier that features a constant-current power supply for amp-embedded sensors, an RMS conversion function, and a band-pass filter.The RMS function in this amp is effective for monitoring the basic frequency level fluctuation in rotation equipment and the fluctuation of the AC power level.For vibration measurement, an amp-embedded charge sensor can be directly connected to this amp unit. For voltage measurement, 500 V (DC or AC peak values)can be directly input. In addition, the band-pass filter offers filtering of necessary frequencies to perform the RMS conversion so that clear waveforms for judgment are available.

This is a DC amp that can acquire data at a high-speed sampling rate of 1 µs. Channels are isolated from each other and have a withstand voltage for input of 500 V max. (DC or AC peak values). This amp contains two channels per unit.

2-ch TC/DC amp (AP11-106)
This amp can be used as a thermocouple amp or DC amp. When temperature measurement using a thermocouple amp and voltage measurement using a DC amp are necessary, this amp is useful because no amp replacement is required. Moreover, five types of thermocouples, R, T, J, K, and W can be connected and high-speed temperature measurement as fast as 10 µs is possible. Channels are isolated from each other and have an input voltage of 50 V max. (DC or AC peak values). This amp contains two channels per unit.
