THE 2408i is a high specification process and temperature indicator with an extensive range of I/O options. A modular hardware build accommodates a range of plug-in modules allowing for up to four alarm outputs, two process value inputs, analog retransmission, remote setpoint input and digital communications.

The 2408i is a 1/8 (48 x 96mm) panel mounting indicator providing full five digit red or green 15.9mm LED display with up to three decimal places allowing for a wide variety of process and temperature inputs. Display units of OC, OK and OF are available.

A universal input allows for nine internally stored thermocouple types (J, K, T, L, N, R, S, B & P) plus Pt100 and process inputs such as 4-20mA, 0-20mA and 0-10V dc, while another 11 thermocouples are available as factory downloadable inputs.

For inputs such as strain gauge or load cell, the 2408i can be fitted with 5V or 10V excitation supplies and for loop-powered field transducers a 24V dc loop supply can also be added.

A second process input card can be fitted for applications where maximum, minimum or differential measurements are required.

Four internal alarms are software configurable for standard high, low and deviation functions and can also be used to alarm on sensor break as well as rate of change alarm.

Alarm function modes of latching, non-latching, blocking and failsafe are also software selectable as is hysteresis or deadband. The blocking function is useful on start-up to prevent unnecessary operator alerts during process start-up.

The alarm outputs can either be either voltage-free relays or high speed logic outputs. The 2408i can also be fitted with logic input cards for applications where the input signal may need to be retransmitted as a dc analog signal such as 4-20mA or 0-10V, and optional dc retransmission card can also be added, replacing the need for an external signal isolation module.

For interfacing to serial communications networks, the 2408i can be fitted with communications cards for DeviceNet, ProfiBus or ModBus (RS232, RS422 and RS485).

Two choices of power supply allow the 2408i to be used in almost all applications. For world-wide ac powered applications, a universal 85-264V ac supply is provided while for low voltage applications, a wide ranging ac/dc supply of 20-29V can be ordered.

The front screen display is IP54 rated to enable the 2408i to be utilised in all standard industrial applications. Eurotherm Australia 02 9634 8444.
